Hi chopin-liszt
thanks for the reply
I'm afraid it was like that when I bought it so not a clue where the missing parts are, but I thought the glass was lovely and was messing around with the light on my mobile phone to get good photos for here when I realized how lovely it looks when light shines through it so yes, a twin fitment would make sense to make the best of this glass

The rim needs to be recessed to end up with an applied light fitment I would think so need to find the fitment first before I find out if it needs adapting to fit it. I would be happy to spend some more money on it, as long as it's not a crazy amount as I do want it lit internally too, it's quality glass so I do want a good job doing on it and am loath to cut it or mess with it at all

Do you think there may be seller at the May national glass fair in Birmingham who may have fittings that were suitable please? I've never been to it so not sure of the extent of variety, but am planning on going next month, thanks
